Check battery voltage, it should be minimum 12.4.
Check the battery cables for corrosion and make sure they're tight.

sounds like the PA has failed, I would have the radio shop serviced

HI,
Did you ensure you put the wires back correctly?
What engine?
Look on Dodge forums for info.

Could be a bad capacitors. Open up the case and see if you have any bulging caps. The second thing I would try is to remove all the ram and reseat each ram stick. The 380 can be fickle about ram placement.

This was a recall issue that was supposed to be fixed, I would bring this into the dealer, they should fix it for free. They had electrical problems with these models, headlights dash lights, and sometimes wipers etc. I would get this checked out before your car brakes down on the road. Hope this helps and good luck. you can also refer to lemonlawclaims.com to check out a few other people that had this issue reported it.

sounds like the power to the echo came loose/ shorted ie.

the body control module has most likely failed, have the dealer test it.

sounds like it needs new bearings, take it to a pool professional.
